Moretools emerged from the Brasília underground with a self-titled debut that fuses death metal, grindcore, thrash, and hardcore into a relentlessly aggressive whole. The band has shared stages with Krisiun, Onslaught, and Torture Squad, and appeared at major festivals including Porão do Rock.

Led by guitarist and vocalist Fabrício Moraes, a veteran of the Brasília metal scene through his work in Dark Avenger and several other local acts, Mortaes debuted in 2007 with the album "Obsessive Visions" on Die Hard Records. The band blends death and black metal with neoclassical guitar flourishes, and the debut featured guest contributions from members of Dr. Sin, Khallice, and Miasthenia.

One of the oldest extreme metal bands in Paraná, Morthal trace their origins to 1987 and are often cited as the pioneer of the death/thrash style in the state, performing shows as far as Brasília and Asunción in the mid-1990s and releasing a split LP with Tumulto in 1992 that drew national attention in the underground press. After roughly 18 years of inactivity, the band reformed with vocalist Nilton Bobato and guitarist Zepa Costa among its ranks, picking up where their gritty, war-themed death/thrash left off.

Mortuário A.D. channels the raw, bestial energy of early Brazilian extreme metal through a death/thrash lens, citing Sepultura, Sarcófago, Mutilator, Vulcano, Obituary, and Hellhammer as touchstones. Their second release, "Die in Pain," dropped on Halloween 2024 and captures the horror-soaked ferocity the band has built its identity around.

A stalwart of the Goiânia metal scene, Mugo mixes death metal heaviness with thrash energy and pronounced groove, drawing comparisons to Obituary and At the Gates. Their discography spans multiple full-lengths including "Go to the Next Floor" (2009), "Race of Disorder" (2017), and "Tempest" (2019), each refining their brand of extreme metal with elaborate harmonies.

Munkill is an extreme metal band from San Carlos de Bariloche, Río Negro, whose founding members include vocalist/guitarist Demogorgon Malignum, bassist Malice Misanthropic, and drummer Sebastian Ortega. Their debut album "Suicide Or Homicide" was recorded at Insight Producciones and released in September 2012, followed by "Ambition and Destruction" in 2020, recorded in quarantine and mixed by Agustin Ortega at Demogorgon Malignum Producciones.

A two-member war machine built around Aubert Mutilator on vocals and programming and Iscariot Destructor on guitars and bass, Mutilação Anticristã traffics in raw, lo-fi black/death metal with an uncompromising anti-Christian and satanic worldview. The duo released "Metal Negro Anticristo" in 2012 and followed it with the even more abrasive "Noite de Sexo Bestial e Profano" in 2014, both recorded in the Sergipe underground without concession to polish or accessibility.

Mythological Cold Towers deal in slow, heavy doom that draws equally from the death-doom tradition and epic doom's grandiose sweep, with lyrical themes orbiting ancient South American civilizations, mythology, and lost monuments. Albums like Immemorial (2011) and Monvmenta Antiqva (2015) display the band's ability to balance crushing heaviness with melodic keyboard passages and an almost archaeological sense of atmosphere.
